Hi
When using BQ25703A to charge the battery in buck mode, with 20V input and 8V output, there is no abnormality in the waveform of the G pole of the two MOS transistors; If it is boost mode, 5V input, 8V output, and the G poles of two MOS transistors overlap, how to solve this situation because there is a platform voltage on the upper transistor；
Hi Tiger
Thank you very much for your answer. I still have some questions to ask
1）I retested the VGS voltage of the upper and lower MOSFETs and found that the dead time for the upper and lower MOSFETs to turn off and on is asymmetric, as shown in Figures 1 and 2. What is the reason for this asymmetry?
2）2) If the dead time is increased by configuring registers, what impact will it have? I understand that it will increase power consumption because of the parasitic diode in the bottom FETs
